Biological Activity

Description Paliperidone, the main active metabolite of Risperidone, is a potent serotonin-2A and dopamine-2 receptor antagonist, used in the treatment of schizophrenia.
Targets
Dopamine receptor [1]
In vitro
In vitro Paliperidone significantly increases the intracellular accumulation of Rh123 and DOX in a concentration-dependent manner. [1] Paliperidone works finely at low concentrations (10 and 50 μM) against Aβ(25-35) and MPP(+) and solely protects SH-SY5Y from hydrogen peroxide. Paliperidone (100 μM) completely diminishes cell reduction induced by different stressors, regardless of their dosages. Paliperidone is demonstrated with higher oxidative stress-scavenging properties than other APDs in several aspects, such as generated bulk glutathione, low HNE, and protein carbonyl productions. [2] Paliperidone enhances dopamine toxicity at the highest dose and is the only AP that significantly increases cell viability (8.1%) compared with cells treated with dopamine alone. [3]
In Vivo
In vivo Paliperidone normalizes prefrontal cortical basal extracellular glutamate in rats. Paliperidone also prevents the acute MK-801-induced increase in extracellular glutamate in rats. [4] Paliperidone coadministered with Escitalopram restores the suppression of the NE neuronal firing rate (n = 5 rats) and the percentage of neurons exhibiting burst firing. [5] Paliperidone results in a dose-dependent decrease in bite and attack behaviors with an effective dose. Paliperidone results in the maximal reduction in aggressive behavior. [6]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
